Method for the analysis and evaluation of the most common failures in the fitting of total lower prosthesis in older adults using Fuzzy Compensatory Logic

Abstract

Older adults present problems in the adaptation of the lower total prosthesis, causing discomfort when eating or speaking, either due to mobility or accumulation of food remains in empty spaces, among the negative aspects are overextended prostheses or biomechanical failures, the prosthesis must guarantee its gum adaptability that in older adults is thin and decreased in height. The objective of this research is to develop a method for the analysis and evaluation of the most common failures in the adaptation of lower total dentures in older adults. The uncertainty process is modeled by Compensatory Fuzzy Logic. A case study is implemented with a population of 60 older adults from the "Señor de los Remedios" gerontological center, data recorded in the Clinical History and data collection form, from which a group of people in rehabilitation is taken to determine your treatment. The status of compliance with the main treatment axis for the different cases analyzed was obtained as a result. In addition, an analysis and clinical evaluation was developed to find out the most common failures of adaptation of the prosthesis. The most relevant results were: 22% presented maladapted lower total prosthesis and 16% presented clinical pictures due to poor adaptation of the prosthesis.
